Intel DX58SO comes with other smaller features, like an on-board power switch, an on-board buzzer (speaker) and a small 40-mm fan for you to install on top of the passive heatsink from the X58 chip if you think it is heating too much.

The voltage regulator circuit uses solid aluminum capacitors and ferrite chokes, which prevent leakage and have a lower energy loss, respectively, and passive heatsinks on top of the transistors.

All capacitors that aren’t solid are Japanese, from Chemi-Con, Nichicon and Sanyo, which is terrific.
